套接字：两次处理连接？

Question

我正在努力解决这个问题，但它实际上是一个令人头疼的问题，套接字是为了与服务器建立两个连接，第二个是合法连接。我有这个方法，我附加到beginReceive方法的回调，虽然它调用Dispose两次？

通常它只调用一次，因为客户端与服务器建立2个连接，第二个是合法的，但似乎这个方法想要调用Dispose两次，这让我觉得有些不对劲，有人可以验证是否有什么错了吗？

private void OnIncomingData(IAsyncResult asyncResult)
{
    int bytesReceived;

    try
    {
        bytesReceived = _socket.EndReceive(asyncResult);
    }
    catch
    {
        Dispose();
        return;
    }

    if (bytesReceived == 0)
    {
        Dispose();
        return;
    }

    try
    {
        var packet = new byte[bytesReceived];
        Array.Copy(_buffer, packet, bytesReceived);

        var received = Encoding.UTF8.GetString(packet);
        var packetData = JObject.Parse(received).ToFlatDictionary();

        var incomingPacket = new IncomingPacket(packetData);
        CoreUtilities.LogToConsole("Received packet: " + incomingPacket.Id + "\n\n" + received);

        if (_session.PacketProvider.PacketEvents.TryGetValue(incomingPacket.Id, out var packetEvent))
        {
            packetEvent.Invoke(_session, incomingPacket);
            CoreUtilities.LogToConsole("Finished executing packet " + packetEvent.GetType().Name + " for " + incomingPacket.Id);
        }
        else
        {
            CoreUtilities.LogToConsole("Failed to execute unknown incoming packet: " + incomingPacket.Id);
        }
    }
    catch
    {
        Dispose();
    }
    finally
    {
        try
        {
            _socket.BeginReceive(_buffer, 0, _buffer.Length, SocketFlags.None, OnIncomingData, _socket);
        }
        catch
        {
            Dispose();
        }
    }
}
